    I am trying to port SGX to Kitkat on Blaze 4460 Platform.

    I have SGX DDK 1.9@2166536 binaries built for Kitkat + 3.4.61 OMAP Kernel

    I am getting SEG Fault with SGX usermode binaries.

    SGX Kernel Binary(pvrsrvkm_sgx540_120.ko) is loading without any issue.

    Please help me in resolving this error.

    Note:
    SGX is working fine with JellyBean
    i.e. no issues using SGX DDK 1.9@2166536 binaries built for JellyBean + 3.4.61 OMAP Kernel

    Hi,

    From the information you’ve given, we can’t tell what has caused the segfault. I’d recommend discussing the issue with TI. They should be able to help you configure the graphics driver for the OMAP platform.

    Regards,
    Joe
